in Thoreau’s Journal:
The snow is the great betrayer. It not only shows the tracks of mice, otters, etc., etc., which else we should rarely if ever see, but the tree sparrows are more plainly seen against its white ground, and they in turn are attracted by the dark weeds which it reveals. It also drives the crows and other birds out of the woods to the villages for food. We might expect to find in the snow the footprint of a life superior to our own, of which no zoology takes cognizance. Is there no trace of a nobler life than that of an otter or an escaped convict to be looked for in the snow? Shall we suppose that that is the only life that has been abroad in the night? It is only the savage that can see the track of no higher life than an otter. Why do the vast snow plains give us pleasure, the twilight of the bent and half-buried woods? Is not all there consonant with virtue, justice, purity, courage, magnanimity? Are we not cheered by the sight? And does not all this amount to the track of a higher life than the otter’s, a life which has not gone by and left a footprint merely, but is there with its beauty, its music, its perfume, its sweetness, to exhilarate and recreate us?
Where there is a perfect government of the world according to the highest laws, is there no trace of intelligence there, whether in the snow or the earth, or in ourselves? No other trail but such as a dog can smell? Is there none which an angel can detect and follow? None to guide a man on his pilgrimage, which water will not conceal? Is there no odor of sanctity to be perceived? Is its trail too old? Have mortals lost the scent? The great game for mighty hunters as soon as the first snow falls is Purity, for, earlier than any rabbit or fox, it is abroad, and its trail may be detected by curs of lowest degree. Did this great snow come to reveal the track merely of some timorous hare, or of the Great Hare, whose track no hunter has seen? Is there no trace nor suggestion of Purity to be detected? If one could detect the meaning of the snow, would he not be on the trail of some higher life that has been abroad in the night? Are there not hunters who seek for something higher than foxes, with judgment more discriminating than the sense of foxhounds, who rally to a nobler music than that of the hunting-horn?
As there is contention among the fishermen who shall be the first to reach the pond as soon as the ice will bear, in spite of the cold, as the hunters are forward to take the field as soon as the first snow has fallen, so the observer, or he who would make the most of his life for discipline, must be abroad early and late, in spite of cold and wet, in pursuit of nobler game, whose traces are then most distinct. A life which, pursued, does not earth itself, does not burrow downward but upward, which takes not to the trees but to the heavens as it home, which the hunter pursues with winged thoughts and aspiration, – these the dogs that tree it, – rallying his pack with the bugle notes of undying faith, and returns with some worthier trophy than a fox’s tail, a life which we seek, not to destroy it, but to save our own. Is the great snow of use to the hunter only, and not to the saint, or him who is earnestly building up a life? Do the Indian and hunter only need snow-shoes, while the saint sits indoors in embroidered slippers?
